Did you, just by any chance, have the pistol in this condition when you were shooting the video? The spring coil that is showing could easily bind on the front of the channel it's in, as that end is quite sharp (sharp enough to chew up the front of the extractor depressor plunger after just a few hundred rounds).
Here's a screen shot I took from your video showing what I am talking about.
Wow! dhgeyer, you get, 'The Catch Of The Day Award'!
I wish I had your eyesight!
Nevertheless, that backwards EDP rod doesn't explain the rub marks on the actual head of Raleigh Glocker's EDP rod. That a backwards rod will adversely affect extraction/ejection is a given. The only question is, 'By how much?'
I've read reports from shooters who had their EDP rods in backwards. In an otherwise properly functioning Glock it didn't seem to make much difference; the Glock still worked. So the question becomes, 'What effect does this mistake have on an improperly functioning Glock pistol?' I'm going to suggest that this would only further weaken already weak ejection; BUT, at no time in the past have I ever heard of this causing a BTF problem. BTF problems with Glock pistols are a relatively recent problem.
NOTE: Raleigh Glocker, if you want to, 'get in bed' with Glock, Smyrna that's entirely your business; but, personally, I'm more careful about whom I sleep with.
